Please use internal links instead of external links where possible.

An internal link is a link that is to another page in this wiki. It looks like

[[Page Name]]

Internal links have many benefits over external links. One of ther benefits is ensuring that the link follows the page if it get moved.

Also, there are interwiki links that can refer to pages in other wiki's. For example, we have an interwiki link setup for [1] using the site code en. These links look like

[[:en:Page Name]]

A real example is en:fair use.

If you want to add an alternate text label to it, have to use a pipe (|) symbol in between the label and the text. For example

[[:en:fair use|read about fair use]] which lookz like read about fair use.
